The CAB client 100 communicates with the CAB server 105 on a terminal, and serves to authenticate a CAB user, synchronize contact information (for example, personal profile information (or PCC) with a converged address book stored in a network storage, and transmit CAB user's requirements (for example, contact subscription, contact search, contact share, interaction with existing contacts, management of user preferences, or the like) to the CAB server 105.

The CAB server 105, a network component in the CAB structure, serves to handle the CAB user's requirements received from the CAB client 100. The CAB server 105, as its features, serves to mutually authenticate a CAB client, store CAB contacts, synchronize contact information, receive updated contact information from a contact subscription function and reflect it in the address book. In addition, the CAB server 105, a network component for subscribing/sharing/converting the contacts and reflecting the user's preference/policy, includes a contact subscription function of receiving information about the number of CAB user preference XML documents and CAB user's subscription request from the CAB user preference App. Usage, a contact share function of applying personal preference of the data obtained through contact subscription, reflecting it in the address book, keeping subscription status information, and sharing the PCC or converged address book, and an interworking function of interworking with the existing address book system and/or exposing an interface to the external enabler. Besides, as for a CAB enabler, the App. Usage includes the CAB AB App. Usage 112 for storing the converged address book and contact status in the XML Document Management (XDM) server that manages user's data, the CAB UP App. Usage 116 for managing user's preference, the CAB FH App. Usage 118 for managing the CAB service request/response, and the CAB PCC App. Usage 114 for storing PCC information. In addition, there are an XDMC for accessing various App Usage functions, a Session Initiation Protocol/Internet Protocol (SIP/IP) Core Network for message routing with entities of the external domain, and a PUSH enabler for sending notification messages of non-SIP terminals.

Specifically, referring to FIG. 1, the key features of the common CAB service include address book synchronization, a contact subscription, contact share, contact search and the like.

1. Address Book Synchronization

In operation 1), if a CAB user modifies a local address book stored in his/her terminal, the CAB client 100 transmits the modified information to the CAB server 105 using a CAB-1 (SyncML) interface. Then, in operation 2), an Address Book (AB) synchronization function 105-1 provided by the CAB server 105 reflects the modifications of the local address book in the CAB AB App. Usage 112 which is a XML document management server, using an XDM agent 105-5. If the CAB client 100 is different from the CAB AB App. Usage 112 in terms of the format, translation may occur, causing a possible data loss due to the translation into another format.

2. Contact Subscription

In operation 1), the CAB client 100 sends an XML Configuration Access Protocol (XCAP) request for contact subscription to the CAB UP App. Usage 116. In operation 2), upon receiving the XCAP request, the CAB UP App. Usage 116 adds a contact address obtained from the XCAP request to a contact subscription list. In operation 3), the CAB UP App. Usage 116 informs a contact subscription function 105-6 in the CAB server 105 of the document change in the contact subscription list due to the additional operation. In operation 4), the contact subscription function 105-6 may send a contact subscription request for the recipient's PCC from the contact subscription list directly to the receiving domain or through a subscription proxy. In operation 5), upon receiving the contact subscription request, the receiving CAB PCC App. Usage 114 checks the access permission and user preference for the contact subscription request, and then informs the recipient of the subscription results. In operation 6), in the case of an environment where the CAP client 100 does not support SIP, the terminal and the enabler may execute the contact subscription using an XDM Document Command Protocol (XDCP).

3. Contact Share

In operation 1), the CAB client 100 sends an XCAP request for contact share to the CAB FH App. Usage 118. Then, in operation 2), the CAB FH App. Usage 118 adds a contact address and a reference to the data to be shared, which are obtained from the XCAP request, in a CAB feature handler. In operation 3), the CAB FH App. Usage 118 informs a contact share function 105-3 in the CAB server 105 of the document change due to the addition of the contact address and the reference to the data to be shared, which are obtained from the XCAP request. In operation 4), the contact status function 105-2 identifies the contact status of the recipient's CAB AB App. Usage 112 based on the recipient's contact. In operation 4-1), if the recipient is a CAB user, the contact share function 105-3 generates a contact share request, and sends the contact share request to a desired target server (for example, CAB AB App. Usage 112 or CAB PCC App. Usage 114) using the XDM agent 105-5. Upon receiving the contact share request, the App. Usage sends shared data to the recipient based on the XDM forward mechanism. In operation 4-2), if the recipient is not a CAB user, the contact share function 105-3 receives data from, for example, the CAB

AB App. Usage 112 or the CAB PCC App. Usage 114, delivers the received data to a CAB interworking function 105-4 to request format translation into the legacy format for the data, and then, sends it to the recipient through a messaging enabler (not shown).

4. Contact Search

In operation 1), the CAB client 100 sends a contact search request for its own AB or PCC, or an AB or PCC of another domain through an aggregation proxy 115 or a search proxy 120 of the XDM enabler. Then, in operation 2), the contact search request is routed to the App. Usage by the search proxy 120, and the App. Usage delivers the search results to the CAB client 100. In operation 3), during external directory search, the CAB client 100 converts the contact search request into an external search request and sends it to the external directory through the interworking function 105-4, and the external directory converts the external search results received through the interworking function 105-4 back into the standard XML search results and delivers them to the CAB client 100.

5. Subscribe to External Address Book from non-CAB System

In operation 1), the CAB client 100 sends an XCAP request for subscription to non-CAB data to the CAB FH App. Usage 118. In operation 2), the CAB FH App. Usage 118 adds the information (for example, information about non-CAB source, credential, scheduled interval, expiration-time and the like) obtained from the XCAP request, in a CAB feature handler. In operation 3), the CAB FH App. Usage 118 informs the interworking function 105-4 in the CAB server 105 of the document changed due to the additional operation of the CAB feature handler. In operation 4), the interworking function 105-4 gets information about non-CAB address book data, stores it in the CAB AB App. Usage 112 depending on the CAB user preference, and then, instructs the CAB client 100 to start AB synchronization.

FIG. 2 is a flow diagram illustrating a common method for updating personal information using an external personal profile according to an embodiment of the present disclosure. Specifically, FIG. 2 illustrates a personal information update method through subscription to external personal profile information.

Referring to FIG. 2, at operation 201, the CAB client 100 stores a “subscribe_profile” request in a CAB Feature Handler App. Usage 110-1, for subscription to external personal profile information from a non-CAB system 115. At operation 202, the CAB server 105 may obtain information about XDM document change by operation 201 from the CAB Feature Handler App. Usage 110-1 thorough document management or document subscription/notification for a predetermined period. At operation 203, an InterWorking Function (IWF) in the CAB server 105 requests subscription to external personal profile information in the non-CAB system 115. At operation 204, the IWF in the CAB server 105 is notified of external personal profile information in the non-CAB system 115. At operation 205, the IWF in the CAB server 105 change a format of the obtained information into CAB format, and then stores it in a PCC App. Usage 110-2. At operation 206, the CAB server 105 stores the results of the request in the CAB Feature Handler App. Usage 110-1. At operation 207, the CAB server 105 receives a response to the request. At operation 208, the PCC App. Usage 110-2 notifies the CAB client 100 of the updated PCC information.

A personal information update method through subscription to external personal profile information in the non-CAB system 115 seems not to be suitable as a common network personal information synchronization method, as it does not provide a personal information update method through user participation/identification and does not provide a way to allow the user to know the reason and time of the change in updated personal information.

A need for implementation of the following requirements has been raised in the background of the disclosure. As in Table 1 below, contact subscription with the external system is managed as the requirements in the current CAB 1.1 standard.

TABLE 1 Label Description Enabler Release CAB-IWG- The CAB Enabler SHALL allow a CAB CAB 1.1 006 User to request the subscription to changes in the user's External Profile at a 3rd party systems to keep PCC up-to-date.

In an embodiment of the present disclosure, by defining an update method for personal information in the CAB system through subscription to external personal profile information in the non-CAB system 115 in order to address the above-described problems, a more efficient personal information management method may be provided to the user.

Specifically, the following methods are proposed in an embodiment of the present disclosure.

1) There is provided a data transmission/reception method and system for providing high-speed communication services without waste of resources, power and memory in a communication system supporting various types of communication services.

2) There is provided a data transmission/reception method and system for providing a CAB service to a user in a communication system.

3) There is provided a data transmission/reception method and apparatus in which a fast and easy CAB service is available depending on the user's choice, by defining an update method for personal information in a CAB system through subscription to external personal profile information in a non-CAB system in the CAB system.

In other words, in an embodiment of the present disclosure, if a CAB server subscribes to external personal profile information in a non-CAB system for update of personal information in the CAB system, the CAB server may store the external personal profile information and status information notified from the non-CAB system in the PCC App. Usage separately from a PCC document, and newly define information about the status of personal information in the CAB system, to update (automatically or manually) the personal information in the CAB system within the user preference, thereby making it possible to provide a more efficient personal information management method to the user. In an embodiment of the present disclosure, it should be noted that the information to be subject to subscription to the external personal profile information in the non-CAB system includes various types of information, such as profiles or contacts of individuals, groups, organizations, companies, and the like.

In an embodiment of the present disclosure, a detailed method related to subscription to personal profile information in a non-CAB system may include a manual update method for personal information in a CAB system using personal profile information subscribed/notified from the non-CAB system according to a first embodiment of the present disclosure, and an automatic update method for personal information in a CAB system using personal profile information subscribed/notified from the non-CAB system according to a second embodiment of the present disclosure. The manual update method for personal information in a CAB system using personal profile information obtained from the non-CAB system according to the first embodiment of the present disclosure includes a manual update method for personal information through a personal information-updated document and a manual update method for personal information through a PCC IDentifier (ID).

FIGS. 3A and 3B are flow diagrams illustrating an example of a manual update method for personal information according to a first embodiment of the present disclosure. Specifically, FIGS. 3A and 3B illustrate a manual update method for personal information through a personal information-updated information document in a CAB system after subscription to external personal information in a non-CAB system.

Referring to FIGS. 3A and 3B, at operation 301, the CAB client 100 sends an XCAP request for subscription to external personal profile information in a non-CAB system to the CAB Feature Handler App. Usage 110-1 in a CAB XDMS. The XCAP request may be represented as the schema illustrated in FIG. 4.

FIG. 4 illustrates an example of a request message for subscription to external personal profile information in a non-CAB system in a CAB FH App. Usage according to an embodiment of the present disclosure. As can be seen in the schema of FIG. 4, the XCAP request at operation 301 indicates a <subscribe-profile> element as an additional sub element of <cab-feature> of the CAB Feature Handler App. Usage 110-1 for subscription to external personal profile information in the non-CAB system. The <subscribe-profile> element may include <non-CAB-source>, <credential>, <expiration-time>, <filter> and the like as its sub elements, and additional sub elements may be created for the expansion of its related functions. The <non-CAB-source> means a non-CAB source including a target Uniform Resource Identifier (URI) for subscription to external personal profile information, the <credential> means a credential for subscription to user's external personal profile information, the <expiration-time> means a valid period of an external personal profile information subscription request, and the <filter> means a filter for selective subscription to external personal profile information.

Referring back to FIGS. 3A and 3B, at operation 302, the CAB client 100 receives a response message (200 OK) from the CAB Feature Handler App. Usage 110-1. At operation 303, the CAB Feature Handler App. Usage 110-1 adds a relevant element from the XCAP request in a CAB Feature Handler Document, and informs the IWF in the CAB server 105 of the document change in the CAB Feature Handler. In addition, the CAB server 105 may be informed of the document change in a CAB Feature Document through active polling for the document. At operation 304, the IWF in the CAB server 105 generates an external personal profile information subscription request (non-cab profile subscribe request) message based on information in the <subscribe-profile> element for a request message for subscription to external personal profile information in a non-CAB system, which is received from the CAB Feature Handler App. Usage 110-1, sends it to the non-CAB system 115, and sets a <code> element, which is a sub element in a <response> element of the <subscribe-profile > element in the CAB Feature Handler App. Usage 110-1, as “pending”. Details about a subscription request for external personal profile information in a non-CAB system and its notification method will not be dealt with, since they are out of the scope of the disclosure.

At operation 305, the IWF in the CAB server 105 receives a notification message for the non-cab profile subscribe request from the non-CAB 115. The response message may be represented as the schema illustrated in FIG. 5.

FIG. 5 illustrates an example of a notification message for the request message for subscription to an external personal profile in a non-CAB system in a CAB FH App. Usage according to an embodiment of the present disclosure. As can be seen in the schema of FIG. 5, the non-CAB system sends, to the CAB system, a notification message including the current version information and detailed update information of external personal profile information for the CAB user's external personal profile information subscription request. Details about a subscription request for external personal profile information in a non-CAB system and its notification method will not be dealt with, since they are out of the scope of the disclosure.

At operation 306 of FIG. 3A, the IWF in the CAB server 105 checks the user preference in the CAB User Preferences App. Usage, for update of PCC information in the CAB system in the notification message. The user preference defined in the CAB User Preferences App. Usage to perform operation 306 indicates whether the IWF will update personal information in the CAB system automatically or manually. If the user preference is set as ‘automatic’, the CAB server may directly update PCC information using external personal profile information subscribed/notified from the non-CAB system without the CAB user's check. If the user preference is set as ‘manual’, the CAB server may finally update PCC information with the CAB user's check. In the first embodiment of the present disclosure, the user preference for update of personal information in the CAB system is assumed to be set as ‘manual’.

At operation 307, the IWF in the CAB server 105 converts or translates an external personal profile notification message received from the non-CAB system 115 into a form suitable to a data format of the CAB system based on a data conversion tool such as a preset data mapping table, and then stores it in the existing PCC document or in new PCC update document in the PCC App. Usage 110-2 in the CAB XDMS in a new PCC form. A PCC update information list document defined below may also be generated and stored in the new PCC document. The PCC update information list document in a PCC document in the PCC App. Usage may be generated separately from the existing PCC information (for example, person details, org. details, and group details). A detailed schema of the PCC update information list document is as illustrated in FIG. 6.

FIG. 6 illustrates an example (manual) of a PCC update information list document in a CAB PCC App. Usage according to an embodiment of the present disclosure.

As can be seen in the schema of FIG. 6, an example of a PCC update information list document in the CAB PCC App. Usage at operation 307 may include elements <update-information>, <pccidref, <time-stamp>, <approval-type>, <update-type>, <source>, and <status> as sub elements of an element <update-information-list>, and additional sub elements may be created for the expansion of its related functions. The <update-information-list> is an element including information about a PCC update information list. The <update-information>, an element including information related to the actual PCC update information, includes an ID attribute for identification of the PCC update information document, may include elements <pccidref>, <time-stamp>, <approval-type>, <update-type>, <source> and <status> as its sub elements, and additional sub elements may be created for the expansion of its related functions. The <pccidref> indicates new PCC information that is generated in the existing PCC document or new PCC update document based on the external personal profile subscription notification message generated at operation 307. If the external personal profile is automatically stored in the existing PCC document after it is converted in the form of PCC, a value of <pccidref> may not be included in the PCC update information list document to prevent duplicate designation of the generated PCC information. The <time-stamp>> means a time for which external personal profile information is notified, the <approval-type> means an update type of the notified external personal profile, and may include, as its sub element values, an value ‘Automatic’ for automatic update of personal information and a value ‘Manual’ for manual update of personal information. The <update-type> means an update type of the PCC update information document, and may include, as its sub element value, a value ‘subscribe_profile’ for subscription to the external personal profile information. The <source> represents a source of the notified external personal profile information, and the <status> represents a status value of an external personal profile information subscription request for the generated PCC personal information document, and may have ‘active’, ‘pending’, ‘denied or other-error’ and the like as its sub element values. In addition, in the case where PCC update information list document is added in the existing user's PCC, if PCC information converted from the external personal profile information overlaps the existing PCC, related information may be included in the PCC update information list document after its duplicate storage, and if the PCC information does not overlap the existing PCC, the converted PCC information is temporarily stored, and then a PCC update information list document may be created, in which a link therefor is included in <pccidref>.

At operation 308 of FIG. 3A, the IWF in the CAB server 105 receives a response message (200 OK) from the PCC App. Usage 110-2 in the CAB XDMS. At operation 309, the IWF in the CAB server 105 updates a <response> element in the CAB Feature Handler Document 110-1 based on the received response message. At operation 310, the IWF in the CAB server 105 receives a response message (200 OK) from the CAB Feature Handler App. Usage 110-1. At operation 311, the CAB client 100 is notified of changes in the PCC App. Usage 110-2 of the CAB user. The information that the CAB client 100 is notified of may be different depending on whether the PCC update information list document at operation 307 is generated or not. For example, in response to a subscription request for external personal profile information in the non-CAB system, (i) the newly generated PCC information in the new PCC update document and the PCC update information list document in the user PCC document may be notified to the CAB client 100; (ii) they may be notified to the CAB client 100 in the form of the newly generated PCC information and the PCC update information list document in the existing PCC document; (iii) they may be notified in the integrated form given by adding the PCC update information list document to the existing user's PCC in the form of sub element, i.e., notified in the form of the user's PCC information and PCC update information list document; or (iv) they may be notified to the CAB client 100 only in the form of the PCC update information list document added in the existing user's PCC document. The newly generated PCC information may be included in a PCC update information list document in the form of a reference link such as ‘pccidref’, as mentioned at operation 307.

At operation 312, the CAB client 100 informs the CAB user of the changes between the newly generated PCC information and the existing PCC information based on the information (for example, the newly generated PCC information in the new PCC update document and the PCC update information list document in the user PCC document; the newly generated PCC information and the PCC update information list document in the existing PCC document; the user's PCC information and the PCC update information list document in the combined form given by adding the PCC update information list document to the existing user's PCC in the form of sub element; or the PCC update information list document added in the existing user's PCC document) notified at operation 311, allowing the CAB user to choose only his/her desired information, and sends the PCC information the CAB user desires to modify and the new PCC information document the CAB user desires to delete, to the PCC App. Usage 110-2 using a XDCP Differential Write request message. If the CAB user is notified of the existing user's PCC information including the added PCC update information list document or of only the added PCC update information list document, the CAB user checks the existing PCC information and the changes using the reference link in ‘pccidref’ for a check of the newly generated PCC information and then, may similarly choose only his/her desired information. An example of the XDCP Differential Write request message at operation 312 may be represented as illustrated in FIG. 7.

FIG. 7 illustrates an example of the XDCP Differential Write request message at operation 312 of FIG. 3B according to an embodiment of the present disclosure.

As can be seen in the schema of FIG. 7, at operation 312, the CAB client 100 sends to the PCC App. Usage 110-2 an XDCP Differential Write request message including the PCC update information that the CAB user was notified of at operation 311, the information (for example, addition of a hobby (e.g., soccer) and deletion of web information (e.g., twitter/joeblogs)) that the CAB user has finally selected based on the existing user's PCC information, and the information for deleting the new PCC information that is stored in the existing PCC document or the new PCC update document at operation 307.
